6600K will not go past 4.7 GHz
I own an Intel 6600K running at 4.7 GHz with a stable voltage of 1.356V. My setup includes an Asus Maximus IX Apex motherboard, a H110i GTX for cooling, and a HyperX Fury 16 GB RAM module. My goal is to reach 5.0 GHz without enabling XMP mode. All other BIOS settings remain at their defaults, except for adjusting the CPU multiplier and voltage. My hardware includes an I5 6600K, 2x8 Corsair Fury 16 GB RAM at 2133 MHz, a Strix GTX 1070 OC, a Corsair HX 750i, and a Samsung SSD 850 EVO 500GB.

I have a Intel 6600K currently at 4.7 GHz at 1.356V (stable)... I have a H110i GTX. My aim is to get to 5.0 GHz.

is correct. 6th Generation Core i was Intel's first 14nm (nanometer) processor. Most top out at 4.8GHz. 7th Generation is known as 14nm+ which is a more refined silicon fabrication allowing many to reach 5.0GHz. 8th Generation is 14nm++ and can reach 5.1GHz.
There is a company which is actually named "Silicon Lottery" that specializes in selling "binned" (and delided) CPU's. Binning refers to the process by which CPU's are tested and sold according to overclocking results. Silicon Lottery is highly experienced and reputable, and...
Have you considered increasing the voltage? My estimate is the maximum safe voltage is 1.4V. If that fails, it might mean the silicon wasn't what it was supposed to be. Thanks for your effort.
I attempted to raise the voltage to 1.4 and above. Also, this is my third 6600K model I've tried to operate at 5 GHz.
I currently have an Intel 6600K running at 4.7 GHz with a stable voltage of 1.356V. My goal is to achieve around 5.0 GHz. WildCard999 is right. The 6th Generation Core i was Intel's first 14nm processor, and most top models reach up to 4.8GHz. The 7th Generation, known as 14nm+, offers a more advanced silicon design, enabling many to hit 5.0GHz. The 8th Generation is 14nm++ and can go as high as 5.1GHz. There’s a company called "Silicon Lottery" that focuses on selling "binned" or "delided" CPUs. Binning describes how processors are tested and categorized based on overclocking results. Silicon Lottery is well-known for its expertise, offering detailed frequency and voltage data on their site: https://siliconlottery.com/collections/a...ucts/delid Overclocking depends mainly on voltage and temperature. Each processor is unique in these aspects—voltage tolerance, thermal response, and overclock potential. This variability leads to the term "silicon lottery," a common phrase among enthusiasts. When adjusting your processor near its highest overclock setting, remember that boosting by 100 MHz typically requires about a 50 millivolt increase in Vcore (0.050) to keep things stable. If you need 70 millivolts or more for the next stable 100 MHz boost, it suggests your processor is being overclocked beyond its limits. Given you’re already at 4.7GHz with a 1.356V core voltage, reaching a stable 4.8GHz without surpassing 1.400 volts seems unlikely. Even in normal conditions (22°C), maintaining reasonable Core temps (around 80°C) during heavy loads like Prime95 v26.6 would be challenging. Keep in mind the importance of balancing overclocking. The jump from 4.7 GHz to 4.8 GHz is only about 2.2%, which doesn’t significantly affect overall performance. Pushing beyond recommended voltage and temperature limits isn’t worth it unless you’re willing to risk instability.
